Photon Echo from Localized Excitons in Semiconductor Nanostructures

Photon-assisted transport in semiconductor nanostructures

In this review we focus on electronic transport through semiconductor nanostructures which are driven by ac fields. Along the review we describe the available experimental information on different nanostructures, like resonant tunneling diodes, superlattices or quantum dots, together with the theoretical tools needed to describe the observed features. These theoretical tools such as, for instan...

Instantaneous Rayleigh scattering from excitons localized in monolayer islands

Semiconductor nanostructures via electrodeposition from ionic liquids*

The fascinating properties of ionic liquids make it possible to synthesize semiconductor nanostructures via a simple and low-cost electrochemical pathway. The present paper summarizes our recent work on the synthesis of Si, Ge, and SixGe1–x nanostructures from ionic liquids: thin films, nanowires and photonic crystals. We also introduce our first results on the template-assisted electrodepositi...

Photon Echo Relaxation In

We have observed deeply modulated photon echoes from Pr 3 ÷ ions in LaF3 reflecting nuclear hyperfine interactions in both the ground 3H 4 and excited 3P o states. We infer splittings of 0.75 MHz and 1.13 MHz for the 3P 0 state, lnhomogeneous broadening of the terminal levels is found to lead to echo modulation damping. A surprising concentration dependence of the photon echo relaxation rate is...
